Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to a connector and a car. Background Art

[0002] At present, during the automobile maintenance process, when the connector needs to be plugged in, it is often necessary to align the connector through the anti-misalignment structure before the connector can be plugged in. The anti-misalignment structure in the prior art often designs an anti-misalignment on the first connector and sets another anti-misalignment on the second connector, and then achieves alignment through point-to-point docking between the two anti-misalignments; the shortcomings of the above scheme are: since the two anti-misalignments are point-to-point docking, it is difficult to locate and align the connector when plugging it in. It is necessary to first carefully observe the specific positions of the two anti-misalignments manually before aligning the two and inserting them. The plugging process is cumbersome and time-consuming; and plugging in before positioning and alignment is performed is likely to cause damage and deformation of the components of the connector, increasing the maintenance cost.

[0038] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0039] In the description of the present invention, it should be understood that the terms "longitudinal", "radial", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] like Figures 1 to 4 As shown, an embodiment of the utility model provides a connector, comprising:

[0042] The first connector 1 comprises a first sheath 11, wherein the first sheath 11 is provided with a guide groove 111 and an arc-shaped opening 112 connected to the guide groove 111; in the direction from the guide groove 111 to the arc-shaped opening 112, the width of the arc-shaped opening 112 gradually increases; specifically, the first connector 1 may be a male connector in a connector; in a further embodiment, as Figure 6As shown, the first connector 1 can be placed in a connecting rod 3 (such as a piston rod of a cylindrical structure of an electromagnetic valve body, in which case the connector is suitable for a built-in electromagnetic valve system of an automobile suspension shock absorber), that is, a receiving space 31 is provided in the connecting rod 3, the first connector 1 is installed in the receiving space 31 to engage with the connecting rod 3, and the first connector 1 can freely rotate axially in the receiving space 31. It can be understood that since the width of the arc-shaped opening 112 gradually increases in the direction from the guide groove 111 toward the arc-shaped opening 112, the opening width of the arc-shaped opening 112 at one end away from the guide groove 111 is greater than the width of the guide groove 111, that is, the arc-shaped opening 112 is trumpet-shaped, and the opening width of the arc-shaped opening 112 at one end away from the guide groove 111 is larger.

[0043] The second connector 2 includes a second sheath 21 with a limiting rib 211 protruding from the outer wall; the limiting rib 211 is used to pass through the arc opening 112 and insert into the guide groove 111 to position and insert the second sheath 21 into the first sheath 11. Specifically, the second connector 2 can be a female connector in a connector.

[0044] When the first connector 1 and the second connector 2 of the connector need to be plugged in, the first sheath 11 is first aligned with the second sheath 21, and then the limiting rib 211 on the second sheath 21 is more easily inserted from the arc-shaped opening 112 with a larger opening width, and then the second sheath 21 is roughly positioned and guided, and the limiting rib 211 of the second sheath 21 is guided to move along the arc-shaped opening 112 toward the guide groove 111, and then the limiting rib 211 passes through the arc-shaped opening 112 and is inserted into the guide groove 11 1, the limiting rib 211 will continue to be precisely positioned and guided along the guide groove 111 that matches the width of the limiting rib 211, that is, the guide groove 111 in this embodiment matches the width of the limiting rib 211, and the width of the guide groove 111 is roughly equal to the widest position of the limiting rib 211, so that the widest position of the limiting rib 211 can be attached to and slide relatively with the inner wall of the guide groove 111, thereby avoiding the shaking of the limiting rib 211 in the guide groove 111, further improving the insertion accuracy. For example, Figure 1 The limiting rib 211 shown in the figure is arrow-shaped, and the width of the arrow portion is the widest. A second abutting arc surface 2111 is provided on the widest arrow portion. The arc-shaped design can make the sliding fit between the arrow portion and the guide groove 111 smoother.

[0045] Among them, the arc-shaped opening 112 and the guide groove 111 of the above-mentioned first connector 1 and the second connector 2 can respectively perform coarse positioning guidance and fine positioning guidance on the limiting rib 211, so that while the limiting rib 211 is easy to plug into the arc-shaped opening 112, the limiting rib 211 can finally be automatically aligned and accurately inserted into the guide groove 111, which is convenient for the plug-in pairing of the first connector 1 and the second connector 2 of the connector.

[0046] In the above embodiment of the utility model, the first sleeve 11 of the first connecting member 1 is provided with a guide groove 111 and an arc-shaped opening 112 connected to the guide groove 111, and a limiting rib 211 is protruded on the outer wall of the second sleeve 21 of the second connecting member 2; since the width of the arc-shaped opening 112 gradually increases in the direction from the guide groove 111 to the arc-shaped opening 112, the opening width of the arc-shaped opening 112 away from the guide groove 111 is greater than the width of the guide groove 111. At this time, since the arc-shaped opening 112 is away from the guide groove 111, the arc-shaped opening 112 is not as wide as the guide groove 111. The opening width at one end of the second sheath 21 is large, and the limiting rib 211 of the second sheath 21 can be easily aligned with the arc-shaped opening 112 with a larger width without careful manual observation, and then the limiting rib 211 is inserted into the guide groove 111 through the arc-shaped opening 112, and finally the second sheath 21 is positioned and plugged into the first sheath 11, so that the first sheath 11 and the second sheath 21 have a specific relative angle and relative position relationship after plugging. The connector of the utility model has a simple structure, a simple plugging process, and is easy to position and align, thereby improving the plugging efficiency. At the same time, after the limiting rib 211 enters the arc-shaped opening 112, even if the limiting rib 211 is not aligned with the guide groove 111 and touches the arc-shaped opening 112 after plugging in, at this time, since the arc-shaped opening 112 is set to be an arc, the limiting rib 211 can continue to slide along the arc-shaped opening 112 after plugging in until it is inserted into the guide groove 111. Therefore, the utility model can also protect structures such as the limiting rib 211 and make them less likely to be deformed and damaged, thereby reducing maintenance costs.

[0047] In one embodiment, if Figure 3As shown, the first sheath 11 is provided with a first installation space 114, and the first connector 1 also includes a first terminal 12 and a first cable 13 both installed in the first installation space 114; the first terminal 12 is connected to the first cable 13; it is understandable that the first installation space 114 is arranged in a direction parallel to the axial direction of the first sheath 11, and at least one first terminal 12 is installed in the first installation space 114, and in some embodiments, the first terminal 12 and the first cable 13 are crimped and riveted. It is understandable that at least a portion of the first terminal 12 is arranged in the first installation space 114 at a position opposite to the guide groove 111; and one end of the first cable 13 away from the first terminal 12 extends out of the first installation space 114. The first installation space 114 can be arranged to be connected to the arc opening 112 and the guide groove 111 according to needs, or it can be not connected to the arc opening 112 and / or the guide groove 111, which is not limited here.

[0048] Furthermore, if Figure 5 As shown, the second sheath 21 is provided with a second installation space 212, and the second connector 2 also includes a second terminal 22 and a second cable 23 both installed in the second installation space 212; the second terminal 22 is connected to the second cable 23; it is understandable that the second installation space 212 is arranged in a direction parallel to the axial direction of the second sheath 21, and at least one second terminal 22 is installed in the second installation space 212, and in some embodiments, the second terminal 22 and the second cable 23 are crimped and riveted. It is understandable that at least a portion of the second terminal 22 is arranged in the second installation space 212 at a position opposite to the limiting rib 211; and one end of the second cable 23 away from the second terminal 22 extends out of the second installation space 212.

[0049] Understandably, if Figure 1 and Figure 2 As shown, the limiting rib 211 passes through the arc-shaped opening 112 and is inserted into the guide groove 111, so as to position and insert the second sheath 21 into the first sheath 11 and realize the docking of the second terminal 22 with the first terminal 12. That is, the first sheath 11 on the connector is provided with the arc-shaped opening 112 and the guide groove 111, and the limiting rib 211 is provided on the second sheath 21, so that the connector has an automatic guiding function, so that the limiting rib 211 is easy to insert into the arc-shaped opening 112, and the limiting rib 211 can finally be automatically aligned and accurately inserted into the guide groove 111, so as to realize the plug-in pairing of the first terminal 12 of the first connector 1 and the second terminal 22 of the second connector 2.

[0050] In one embodiment, if Figures 1 to 3As shown, the first sheath 11 includes at least two arc-shaped openings 112 arranged at intervals, and at least two guide grooves 111 connecting the arc-shaped openings 112; each of the arc-shaped openings 112 includes two arc-shaped guide surfaces 1121 arranged on opposite sides of the guide groove 111; the first sheath 11 also includes at least two guide arc surfaces 113, each of the guide arc surfaces 113 is connected between the arc-shaped guide surfaces 1121 of two adjacent arc-shaped openings 112; the guide arc surface 113 is located at one end of the arc-shaped guide surface 1121 away from the guide groove 111. It can be understood that in this embodiment, the guide arc surface 113 is used to guide the limiting rib 211 inserted into this position to the arc-shaped guide surfaces 1121 of the arc-shaped openings 112 connected to it on both sides, so that the limiting rib 211 can finally still enter the guide groove 111. In a specific embodiment, as Figure 3 As shown, in the direction of the guide groove 111 toward the arc-shaped opening 112, the distance between the guide arc surface 113 and the center line of the guide groove 111 gradually increases, so as to guide the limiting rib 211 inserted into the guide arc surface 113 to the arc-shaped guide surface 1121 of the arc-shaped opening 112 connected to it on both sides.

[0051] That is, two or more arc-shaped openings 112 may be provided on the first sheath 11 (in Figure 1 In the embodiment shown, the number of the arc-shaped openings 112 is two, and a guide arc surface 113 is provided between the arc-shaped guide surfaces 1121 of two adjacent arc-shaped openings 112, so that the port of the entire first sheath 11 away from the guide groove 111 forms an annular guide surface surrounded by the arc-shaped opening 112 and the guide arc surface 113. It should be noted that the number of guide grooves 111 should be equal to the number of arc-shaped openings 112; and the number of limiting ribs 211 on the second sheath 21 should be consistent with the number of guide grooves 111. In this way, since the port of the entire first sheath 11 away from the guide groove 111 has a guiding function, even in the worst case, when the second sheath 21 and the first sheath 11 are plugged at a very inclined angle, the limiting ribs 211 can be aligned one by one and plugged into the guide groove 111, thereby matching the first terminal 12 and the second terminal 22 of the connector.

[0052] In one embodiment, if Figure 3As shown, on the cross section where the center line of the first sheath 11 is located, the angle θ between the tangent of the guide arc surface 113 and the center line of the first sheath 11 is less than the preset acute angle. The preset acute angle is set according to the requirements, for example, the preset acute angle can be 30 degrees. In this way, only by ensuring that the angle θ between the tangent of the guide arc surface 113 and the center line of the first sheath 11 is less than 30 degrees, can the limiting ribs 211 inserted into the guide arc surface 113 be smoothly guided to the arc guide surfaces 1121 of the arc openings 112 connected to them on both sides, thereby ensuring that the second sheath 21 is smoothly plugged into the first sheath 11.

[0053] In one embodiment, if Figures 1 to 4 As shown, a first abutting arc surface 1111 is provided on the end surface of the guide groove 111 away from the arc-shaped opening 112; and a second abutting arc surface 2111 is provided on the end of the limiting rib 211 close to the first abutting arc surface 1111. The second abutting arc surface 2111 and the second abutting arc surface 2111 need to be ensured to be rounded and smooth arcs, so that after the limiting rib 211 on the second sheath 21 passes through the house opening and enters the guide groove 111, the limiting rib 211 sliding along the guide groove 111 can finally abut against the first abutting arc surface 1111 of the first sheath 11 through the second abutting circular arc, so that while it is convenient to confirm that it is currently plugged in place, the connector is protected from damage by the second abutting arc surface 2111 and the rounded and smooth arcs on the second abutting arc surface 2111.

[0054] In one embodiment, if Figure 3As shown, the first sleeve 11 is provided with a first slot 115 connected to the first installation space 114; the first terminal 12 is provided with a first elastic member 121; the first elastic member 121 is used to extend into the first slot 115 to position the first terminal 12 when the first terminal 12 is installed to the first preset position in the first installation space 114. That is, in this embodiment, when installing the first terminal 12 in the first installation space 114, it is necessary to insert the first terminal 12 into the first installation space 114 and push the first terminal 12 forward so that the first elastic member 121 moves toward the first card slot 115, and when the first elastic member 121 moves in the first installation space 114, it abuts against the inner wall of the first installation space 114. When the first elastic member 121 moves to be opposite to the first card slot 115 (that is, when the first terminal 12 is installed to the first preset position), the first elastic member 121 is no longer restricted by the inner wall of the first installation space 114, and thus pops out into the first card slot 115 under the action of its own elastic force. At this time, it means that the first terminal 12 has been plugged in place. In a further embodiment, a first abutting step is further provided on the inner side wall of the first installation space 114. When the first elastic member 121 pops out and extends into the first card slot 115, the first terminal 12 will also abut against the first abutting step, so that the freedom of the first terminal 12 in the direction of moving forward is limited by the first abutting step, and the freedom of the first terminal 12 in the direction of moving backward is limited by the first spring sheet extending into the first card slot 115, so that the first terminal 12 will be positioned and cannot move forward and backward. It is understandable that when the first terminal 12 needs to be removed from the first installation space 114, it is necessary to press the first elastic member 121 in the first card slot 115, and at the same time push the first terminal 12 to move backward, so as to push it out of the first installation space 114. It is understandable that the first elastic member 121 includes but is not limited to a spring tongue, etc.

[0055] In one embodiment, if Figure 3As shown, the first sleeve 11 is provided with a first locking arm 116 and a first clamping portion 117; the first locking arm 116 is used to clamp with the first clamping portion 117 to press the first terminal 12 when the first terminal 12 is installed to the first preset position in the first installation space 114. It can be understood that when the first terminal 12 is installed to the first preset position, it means that the first terminal 12 has been installed in place in the front-to-back direction, but the axial rotational freedom of the first terminal 12 has not been restricted. At this time, the first locking arm 116 can be clamped with the first clamping portion 117 to clamp the first terminal 12, thereby limiting the axial rotational freedom of the first terminal 12, and further limiting the front-to-back movement of the first terminal 12; that is, the first terminal 12 can be fixedly installed in the first installation space 114 through the clamping arrangement of the first locking arm 116 and the first clamping portion 117. It is understandable that when the first terminal 12 needs to be removed from the first installation space 114, it is first necessary to lower the first locking arm 116 to disengage the first clamping portion 117, and then press the first elastic member 121 in the first clamping groove 115, while pushing the first terminal 12 backward to push it out of the first installation space 114.

[0056] In one embodiment, if Figure 5As shown, the second sleeve 21 is provided with a second slot 213 connected to the second installation space 212; the second terminal 22 is provided with a second elastic member 221; the second elastic member 221 is used to extend into the second slot 213 to position the second terminal 22 when the second terminal 22 is installed to the second preset position in the second installation space 212. That is, in this embodiment, when installing the second terminal 22 in the second installation space 212, it is necessary to insert the second terminal 22 into the second installation space 212 and push the second terminal 22 forward so that the second elastic member 221 moves toward the second card slot 213, and when the second elastic member 221 moves in the second installation space 212, it abuts against the inner wall of the second installation space 212. When the second elastic member 221 moves to be opposite to the second card slot 213 (that is, when the second terminal 22 is installed to the second preset position), the second elastic member 221 is no longer restricted by the inner wall of the second installation space 212, and thus pops out into the second card slot 213 under the action of its own elastic force. At this time, it indicates that the second terminal 22 has been plugged in place. In a further embodiment, a second abutting step is further provided on the inner side wall of the second installation space 212. When the second elastic member 221 pops out and extends into the second card slot 213, the second terminal 22 will also abut against the second abutting step, so that the freedom of the second terminal 22 in the direction of moving forward is limited by the second abutting step, and the freedom of the second terminal 22 in the direction of moving backward is limited by the second elastic sheet extending into the second card slot 213, so that the second terminal 22 will be positioned and cannot move forward and backward. It is understandable that when the second terminal 22 needs to be removed from the second installation space 212, it is necessary to press the second elastic member 221 in the second card slot 213, and at the same time push the second terminal 22 to move backward, so as to push it out of the second installation space 212. It is understandable that the second elastic member 221 includes but is not limited to a spring tongue, etc.

[0057] In one embodiment, if Figure 5As shown, the second sheath 21 is provided with a second locking arm 214 and a second clamping portion 215; the second locking arm 214 is used to clamp with the second clamping portion 215 to press the second terminal 22 when the second terminal 22 is installed to the second preset position in the second installation space 212. It can be understood that when the second terminal 22 is installed to the second preset position, it means that the second terminal 22 has been installed in place in the front-to-back direction, but the axial rotational freedom of the second terminal 22 has not been restricted. At this time, the second locking arm 214 can be clamped with the second clamping portion 215 to clamp the second terminal 22, thereby limiting the axial rotational freedom of the second terminal 22, and further limiting the front-to-back movement of the second terminal 22; that is, the second terminal 22 can be fixedly installed in the second installation space 212 through the clamping arrangement of the second locking arm 214 and the second clamping portion 215. It is understandable that when the second terminal 22 needs to be removed from the second installation space 212, it is first necessary to lower the second locking arm 214 to disengage the second clamping portion 215, and then press the second elastic member 221 in the second clamping groove 213, while pushing the second terminal 22 backward to push it out of the second installation space 212.

[0058] In one embodiment, if Figure 5 As shown, the second sheath 21 is also provided with a sealing groove 216 connected to the second installation space 212; the second connector 2 also includes a first sealing ring 24 and an end cover 25; the first sealing ring 24 is sleeved on the second cable 23 and interference-fitted in the sealing groove 216; the end cover 25 is installed on the second sheath 21, and the end cover 25 is located at the end of the sealing groove 216 away from the second installation space 212 to limit the axial position of the sealing ring. Among them, the inner annular surface of the first sealing ring 24 is interference-connected with the second cable 23, that is, the first sealing ring 24 is interference-fitted on the second cable 23, and at the same time, the outer annular surface of the first sealing ring 24 is interference-connected with the inner side wall of the sealing groove 216, so that the first sealing ring 24 is interference-fitted in the sealing groove 216, so as to achieve the sealing of the second installation space 212, and as shown in FIG. Figure 5 As shown, a through hole is provided in the middle of the end cover 25 for the second cable 23 to pass through. In this way, the end cover 25 is installed at one end of the sealing groove 216 away from the second installation space 212 to position and seal the first sealing ring 24 in the sealing groove 216.

[0059] Furthermore, if Figure 4 and Figure 5As shown, the second connector 2 further includes a tail cover 29 mounted on the second sheath 21, and the tail cover 29 protects the components installed in the second sheath 21. It can be understood that the connection between the tail cover 29 and the second sheath 21 includes but is not limited to snap-on connection. The material of the tail cover 29 includes but is not limited to plastic.

[0060] In one embodiment, if Figures 4 to 8 As shown, the second connecting member 2 also includes a second sealing ring 26 sleeved on the second sheath 21, and a clamping arm 27 installed on the outer wall of the second sheath 21; a clamping gap 28 is formed between the clamping arm 27 and the second sealing ring 26; the connector also includes a connecting rod 3, and the connecting rod 3 includes a accommodating space 31 with a connecting port; the first connecting member 1 is installed in the accommodating space 31, and the arc-shaped opening 112 is connected to the connecting port; when the second sheath 21 is positioned and plugged into the first sheath 11, the connecting rod 3 is plugged into the clamping gap 28.

[0061] That is, the first connector 1 can be placed in the connecting rod 3 (such as the piston rod of the cylindrical structure of the electromagnetic valve body, in which case the connector is suitable for the built-in electromagnetic valve system of the automobile suspension shock absorber), that is, the connecting rod 3 is provided with a receiving space 31, the first connector 1 is installed in the receiving space 31 to be snap-fitted with the connecting rod 3, and the first connector 1 can rotate freely axially in the receiving space 31. Specifically, the second sealing ring 26 is sleeved on the outer surface of the second sleeve 21 with an interference fit, and a stop step is provided on the outer surface of the second sleeve 21, and then, after the second sealing ring 26 is sleeved on the second sleeve 21, it abuts against the stop step to limit the axial movement of the second sealing ring 26. It can be understood that after the second sheath 21 is inserted into the first sheath 11 located in the accommodating space 31 of the connecting rod 3, the first terminal 12 will be plugged into and matched with the second terminal 22, and at the same time, the connecting rod 3 will be plugged into the clamping gap 28 formed between the second sealing ring 26 and the clamping arm 27 to achieve double plug-in and seal the connection position between the first terminal 12 and the second terminal 22 at the same time.

[0062] In one embodiment, if Figure 4 , Figure 5 and Figure 8As shown, the clamping arm 27 includes a support beam 271 and a clamping portion 272 and a pressing portion 273 respectively arranged on opposite sides of the support beam 271; the clamping gap 28 is surrounded by the clamping portion 272, the second sealing ring 26 and the support beam 271. It can be understood that after the connecting rod 3 is inserted into the clamping gap 28, the clamping portion 272 will clamp the outer wall of the connecting rod 3, thereby realizing a stable connection between the connecting rod 3 and the second connecting member 2. Since the support beam 271 and the clamping portion 272 and the pressing portion 273 arranged on opposite sides of the support beam form a structure similar to a lever, when the above connector needs to be disassembled, the pressing portion 273 can be first pressed toward the direction of the second sealing ring 26, thereby causing the clamping portion 272 to tilt around the support beam 271 toward the direction away from the second sealing ring 26. At this time, the clamping gap 28 becomes larger, and the connecting rod 3 can be removed from the clamping gap 28. Furthermore, a guiding inclined surface 2721 is provided on the clamping portion 272 to guide the connecting portion inserted into the clamping gap 28 .

[0063] Furthermore, an annular groove 32 is provided on the outer circumference of the connecting rod 3, and after the connecting rod 3 is inserted into the clamping gap 28, the clamping portion 272 will be clamped in the annular groove 32, thereby realizing a stable connection between the connecting rod 3 and the second connecting member 2. When the connector needs to be disassembled, the pressing portion 273 needs to be pressed toward the second sealing ring 26, thereby causing the clamping portion 272 to tilt around the support beam 271 toward a direction away from the second sealing ring 26. At this time, the clamping portion 272 can be disengaged from the annular groove 32, and the clamping gap 28 becomes larger, and the connecting rod 3 can also be disengaged from the clamping gap 28.

[0064] The utility model also provides a car, comprising the above connector.

[0065] In the automobile of the above embodiment of the utility model, the first sleeve 11 of the first connecting member 1 is provided with a guide groove 111 and an arc-shaped opening 112 connected to the guide groove 111, and the outer wall of the second sleeve 21 of the second connecting member 2 is provided with a limit rib 211; since the width of the arc-shaped opening 112 gradually increases in the direction from the guide groove 111 to the arc-shaped opening 112, the opening width of the arc-shaped opening 112 away from the guide groove 111 is greater than the width of the guide groove 111. At this time, since the arc-shaped opening 112 is away from the guide groove The opening width at one end of 111 is large, and the limiting rib 211 of the second sheath 21 can be easily aligned with the arc-shaped opening 112 with a larger width without careful manual observation, and then the limiting rib 211 is inserted into the guide groove 111 through the arc-shaped opening 112, and finally the second sheath 21 is positioned and plugged into the first sheath 11, so that the first sheath 11 and the second sheath 21 have a specific relative angle and relative position relationship after plugging. The connector of the utility model has a simple structure, a simple plugging process, and is easy to position and align, thereby improving the plugging efficiency. At the same time, after the limiting rib 211 enters the arc-shaped opening 112, even if the limiting rib 211 is not aligned with the guide groove 111 and touches the arc-shaped opening 112 after plugging in, at this time, since the arc-shaped opening 112 is set to be an arc, the limiting rib 211 can continue to slide along the arc-shaped opening 112 after plugging in until it is inserted into the guide groove 111. Therefore, the utility model can also protect structures such as the limiting rib 211 and make them less likely to be deformed and damaged, thereby reducing maintenance costs.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
